CHARLES W. PAGKER, OF PHILADELPHIA, PENNSYLVANIA.

ICE-CREAM FREEZ'ER.

SPECIFICATION forming part of Letters Patent No. 272,752, dated February 20, 1883.

Application filed December 15, 1882. (No model.)

To all whom it may concern Be it known that I, CHARLES W. PAOKER, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Ice-Cream Freezers, of which the following is a specification.

The object of my invention is to provide simple, cheap, and effective driving mechanism for ice-cream freezers of small size, and this object I attain in the manner which I will now proceed to describe, reference being bad to the accompanying drawings, in wh ich Figure 1, Sheet 1, is a vertical section of an ice-cream freezer with my improvements Fig.

2, a plan view of part of the same; Fig. 3, a sectional plan on the line 1 2, and Fig. 4 a perspective view of part of the driving-gear and its hearing.

A is the bucket or tub of the freezer, and B the cream-can, the bottom of the latter having a projecting lug adapted to a socket on the bottom of the tub, as usual, and the cover D of the can having a central spur-wheel, E, cast upon it, the hub a of this wheel receiving the dasher-spindle b, and being adapted to an opening, (I, in the cross-bar F of the tub, as shown in Fig. l. The crossbar is secured to the hub by means of the notched bolts 0 and turn-bucklesf, and in said bar is formed an opening, 9, in which is secured a sleeve, h, forming a bearing for the spindle t' of a pinion. G, adapted to gear into the spur-wheel E on the cover of the can, the spindle and its pinion being supported in the proper position by a pin, m, passing transversely through the spindle, and bearing on the top of the sleeve h, as shown in Fig. I. The pin mis protected and an additional bearing for the spindle t is afforded by a cap, 92, forming part of a plate, J, secured to the cross-bar F, said plate also covering the opening d in the cross-bar, and having an oritice for the reception of the squared upper end of the dasher-spindle b. The upper end of the spindle'i is also squared for the reception of a crank, whereby the said spindle can be turned so as to rotate the can B, a lug in which engages with a lug on the cover D, as usual, the dasher being prevented from turning by the engagement of its spindle with the orifice in the plate J. The sleeve h is driven into the openingg in the crossbar F, and said sleeve may have one or more spurs, p, to prevent it from-turning in the opening, the interior of the sleeve being preferably grooved, so as to lessen the friction on the spindle i, or provide a receptacle for lubricating material. a

By adapting the hub a of the spur-wheel E to an opening, d, in the cross-bar F a bearing is afforded for the upper end of the can when the dasher and its spindle have been removed, so that the can alone can be rotated, as is desirable in some cases. 1

A detachable collar on the spindlet' may be used as the equivalent of the pin m,- but the latter is preferred as the simplest device for the purpose.

I claim as my invention- 1. The combination ofthe can and its cover, having a spur-wheel, E, the spindle t', having a pinion, G, and pin m, the cross-bar F, and a sleeve, h, adapted to an opening in said crossbar, and forming a bearing for the spindle i, as set forth.

2. The combination of the crossbar F, the dasher-spindle b, the spindle 'i, the bearing h, and the plate J, having a cap, it, and an openiug for the reception of the dasher-spindle, as set forth.

3. The combination of the tub and its cross bar F, having an opening, d,-the can having a cover with spur-Wheel E, the hub of which is adapted to the opening, and gearing for rotating the can, as set forth.

In testimony whereo't'I have signed my name to this specification in the presence of two subscribing witnesses.
